Disclosed is an omnidirectional treadmill which has several connected belt units with supporting frames and endless belts which are moved revolving in the first spatial direction. In the second spatial direction, the endless belts of the belt units are moved. The endless belts are driven in the second spatial direction preferably by gear wheels mounted on rolls and by a toothed shaft. The movement of all endless belts is synchronized by coupling with special tooth form crown gears arranged between the belt units.

In some embodiments, a movement platform may be used to develop force models for the determination of movement based on force patterns received from the movement platform. A force model is made by comparing a known user movement to force readings recorded during the user movement. Movement platform force readings may be compared to a plurality of force models to determine a user movement. Once a matching force model is determined, the matching force model may be used to generate instructions for moving a user on the movement platform.

A treadmill is provided. The treadmill includes a frame; a first side support coupled to and extending substantially vertically upwards relative to the frame; a second side support coupled to and extending substantially vertically upwards relative to the frame; and a handrail assembly having a first side coupled to the first side support and a second side coupled to the second side support, each of the first and second sides of the handrail assembly comprising upper and lower members vertically spaced from one another and front and rear push members spaced apart from one another along a longitudinal length of the treadmill, the front and rear push members coupling the upper and lower members, and collectively providing a plurality of hand placement positions including at least two substantially horizontally aligned hand placement positions and at least one primarily vertically aligned hand placement position.

A motion device for a virtual reality interaction includes a core, a running belt carried by the core and a frame. The running belt is configured to wrap the core and capable of sliding on the outer surface of the core. The running belt includes a number of running belt units. A surface of each running belt unit facing the core is provided with a number of grooves, and each groove of each running belt unit is connected with a corresponding groove of an adjacent running belt unit through an elastic strap. The frame is located at a periphery of the running belt and is configured to carry the running belt and the core. A number of first balls are arranged between the frame and the running belt.

Systems, methods, and storage media for navigating in a virtual environment considering imprecision from a user's inner ear vestibular systems. Exemplary implementations may define a point of view for a user in the virtual environment; when the user walks in a real environment, define a vector r1 therein and compute a first vector vr1 in the virtual environment from r1 with vr1 having an x component, ay component and a rotational component ; in real-time priority processing and while user walks, compute a second vector vr2 in the virtual environment having an x-translation component x, a y-translation y component and a rotational component with at least one of x, y and being effective for inducing a translation and/or rotation of the point of view in the virtual environment while the user walks; and move the point of view along vr1 taking into account vr2.

A gait training device includes a treadmill including a belt and rolling parts, and a frame on which the treadmill is mounted, the rolling parts including: a plurality of balls distributed around a central core, and a cage enclosing the plurality of balls in order to keep the balls on the central core while allowing them to be movable relative to the central core, the belt being able to slide over the balls and rotate the balls on the central core.

The disclosure relates to a Virtual Reality (VR) omnidirectional body motion input platform. The VR omnidirectional body motion input platform includes a universal treadmill. An upright post is provided on a side of the universal treadmill; a cantilever located above the universal treadmill is provided on the upright post; a suspension frame extending downward is connected to the cantilever; and a body restriction mechanism located above the universal treadmill is connected to a lower end of the suspension frame.

In some embodiments, a movement platform may be used to develop force models for the determination of movement based on force patterns received from the movement platform. A force model is made by comparing a known user movement to force readings recorded during the user movement. Movement platform force readings may be compared to a plurality of force models to determine a user movement. Once a matching force model is determined, the matching force model may be used to generate instructions for moving a user on the movement platform.

A system for combining six degree of freedom (6DOF) inputs, or positional and orientation inputs, from multiple 6DOF controllers in an augmented reality (AR) environment and/or a virtual reality (VR) environment is provided. In response to the detected movement of multiple controllers, and in particular, rotational movement of the multiple controllers providing user inputs in a virtual reality environment, the detected movements of the multiple controllers may be resolved to a single, common coordinate system to determine intended input to be applied to a selected virtual object in the virtual environment. The ability to resolve these inputs from multiple 6DOF controllers to a common coordinate system may provide a more natural user input mode, thus enhancing the user's experience.

An omnidirectional treadmill apparatus. The omnidirectional treadmill apparatus includes: a plurality of segments which are continuously arranged along the direction of a first axis, each of which having a belt part; a first rotation unit for rotating the plurality of segments along the direction of the first axis; and a second rotation unit for rotating the belt part of each segment in the direction of a second axis which is perpendicular to the first axis, wherein the belt part has a toothed surface which is tooth-engaged with the second rotation unit.
